Wl-i EELED DUMPlNG-SCRAP ER.

SPECIFICATION forming part of Letters Patent No. 390,374. dated October2, 1888.

(No model.)

To all whom, it may concern.-

Be it known that I, GYRUs A. KENNEY, of Nicholasville, in they county ofJessamineand State of Kentucky, have invented a new and Improved WheeledDumping Scraper, of which the following is a full, clear, and exactdescription.

The present invention relates to a scoop or scraper which is supportedon wheels, and is adapted to be lowered to presentits scoopingedge tothe ground for filling, for being raised to a greater or less height,and to be dumped backwardly; and it consists in a combination of themechanisms and of the constructions and combination ofpartsthereof,substantially as will hereinafter more fully appear, and bepointed out in the claims.

Reference is to be had to the accompanying drawiugsfiormingapartofthisspecification,in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of the wheeled scoop, showing thescoop-body as raised with its rear end closed for carrying the load, andbydotted lines its position for dumping, with the tail'board or reargate as held in its opened position. Fig. 2 is a rear elevation ofthesame, with parts at one side broken away the better to illustrate theconstruction of the scoop-elevating drum-shaft clutching mechanism, theclutches thereof being shown as disengaged. Fig. 3 isa centrallongitudinal section through the same on line so or of Fig. 2, but withthe scraper-body as dropped into its position for scooping; and Fig. 4,sheet 2, is a view in rear elevation illustrating the changed positionof some of the parts for shifting the clutching mechanism.

The wheels A. A are mounted on the outwardlyprojecting axles B at thelower end of standards 0 G of an arch-frame formed by said standards anda crossbar, O and said standards are provided on their inner sides withflanges or ways D, upon which flanged rollers F carried by the guidingand embracing arms or clasps E of asupporting-framc, F, run,saidsupporting-frame consisting of side bars, F and a cross-brace, F, heldabove the horizontal line of the side bars, F, by uprights F*, said sidebars, F, having extending downwardly from an intermediate portion ateach side thereof rigid arms F, to which the scoop or scraperbody G ispivotally hung forward of the center,asbyits trunnions G,passinglooselythrough said arms F, and provided with suit able retaining shoulders orcollars, said scoopbody consisting of bottom G, with forward edgesuitably beveled for taking to the ground, sides G formed integral withthe bottom, and opening and closing rear gate or tail-board, G; and fromthe ends of a crossbrace, H, of the tongue H or thills arerearwardly-extending draft-bars H, passing through verticalguiding-slots in vertical bars F, extending from and above the sidebars, F and pivoted at a point, I), of said scoop frame bars F inadvance of the central portion of the scoop-body, said bars H continuingforward inwardly until theyjoin and are secured to the tongue H and froma forward portion of the tongue to the central portion of the crossbar(l of the axle-arch is extended a brace-plank, 11*, se cured at itsforward end to said tongue by a headed screw or bolt, f, passing througha shoe, H of the brace-plank and to the said crossbar G by car-pieces H,pivoted to lugs G of said cross-bar, and thus when the scoopframe issuspended in either its raised or lowered position from parts on. theaxlearch uprights, as hereinafter described, said uprights are by saidbrace-plank always held substantially at right angles to the tongue.

A transverse drum-shaft, K, is horizontally supported insuitablejournals, K, of the axlearch uprights, on which shaft the drumsK are keyed or otherwise secured, each drum being provided with aratchet-wheel, K formed thereon, as shown, or secured thereto, and toeach drum K is fastened the end of a chain, K or other similar flexibleconnection, from the outer ends of which chains the scoopframe F is hungat g. A paw], m, is provided at each ratchet-wheel K, keyed upon acommon horizontal pawl-shaft, an, rotatably supported on the front sideof the axle-arch cross-bar G a radial lever-arm, m, withrearwardly-extended handle or, being provided for convenience inthrowing said pawls out of engagement with their respectivedrum-ratchets, a coiled spring, m secured to a part of the pawl-shaft byone end and to a part of the axlearch by its outer end, retaining saidpawls in their engagement with the ratchets K in a well-known manner.Near each end of the drum-shaft K is keyed a clutch-sleeve, K, with itsclutch-teeth 19 toward the outer ends of said shaft, outside of which,playing loosely inwardly and out-wardly on the shaft, are clutchsleevesK, with clutch-teeth r toward the teeth of the clutches K, a spring, 70,between the inner face of a flange, Z, of the drum-shaft and the outerface of each sliding clutch-collar forcing said clutches K inwardly intoengagement with the clutches K, except when forced outwardly, as will beexplained hcreinafter.

Each moving clutch-sleeve K is provided with sprockets K driven byendless sprocketehains K from a sprocket-wheel,- A, on the hubs ofwheels A.

There is pivoted to a projection, 12, of each upright O avertically-extending arm, L, having a strap or yoke, L, looselyembracing the fixed clutch collar K and continued upwardly therefrom,terminating in about the horizon tal line of the top rear edge ofcross-bar O, to the outer end, p, of which connectingrods L are pivoted,said connecting-rods extending inwardly therefrom and pivoted ateccentric points, as at p, of a disk, L, centrally pivoted to the rearside of the cross-bar 0', having an.

extended arm, L, for convenience in moving it, and its journal or pivotL has a radial or cranked arm, L, to the end of which one end of aspring, L is secured, which by its other end is fastened to aprojection, q, of cross-bar G", the turning of said disk L through theconnectingrods L carrying the ends 19 and yokes L" of arms L inwardlyout ofbearing upon the overlying annular flange K of the movingclutch-collars K, permitting them, under the recoil of the spring is, tobe thrown into engagement with the clutches K.

The vertical arms L are provided between their lower pivotal points andtheir yoke portions with inclined edges L projecting inwardly in avertical plane intersected by that of the outer end of a projection, E",on the scoop-frame guidingclasp E, so that as the scoop-frame rises andforces the arms L outwardly the connecting'rods L partially rotate thedisk L' sulficicntly to carry the radial arm L off the dead-center.(Indicated in Fig. 4.) The reaction of the spring L then secures such afarther rotation of the disk and projection of the connecting-rods thatthe clutches K are forced outwardly against their springs and theremaintained by the excess of pressure of said spring L over theclutch-springs k.

When the clutches K are placed in engage ment with the drum-clutches bythe turning of the lever-arm L therefor into the position shown in Fig.4, to permit the clutches K under the reaction of their springs k, toslide into such engagement to secure, under the retation of the wheelsthrough the sprocket-conv nections described, the rotation of thedrumshaft and the winding of chains and raising of scoopframe and scoop,the said projections E of the rising scoop-frame F abut against saidinclined edges L of the vertical lever-arms L, and said arms are thrownoutwardly, their yoke portions forcing the movable clutches K outwardlyagainst their springs 7c, and out of engagement with the clutches K,thus terminating the winding of chains K upon the drums and theraisingof the scoop. Pressing downwardly on the outer end of the pawlshaft armm releases the pawls from their ratchets and leaves the dru m-shaft freefor the unwinding of the chains and descent of the scoop under itsweight.

The rear gate, G, of the scoop body is hung by upwardly-extendingarmstthereof, pivoted, as at t, to the upper ends of arms 15*, extendedabove the scoop-sides G at the rear portions thereof, said gate by itsends 25 lying against the rear ends ofsaid sides, its bottom edge, 25',lying'slightly in advance of the rear end of the scoop-bottom G, and itis provided with a bolt, G, playing through sockets t, secured on thegate, having a lug, 1, against which a spring, t secured by its oneportion to the gate, bears by its free end to force said bolt downwardlyto project its lower end through a hole or socket, i, in the rear end ofthe scoop-bottom; and a chain, G, by its lower end secured to the lug tof said bolt, and its upper end to an upwardly and outwardly extendedarni,ll ,ofthe crossbar F,serves, when the seoopbody is tippedbackwardly on the trunnion G, to draw the bolt from the socket, and asthe rear of the scoop tilts downwardly and inwardly, maintaining thelower end of the gate within the range of the chain, it is caused toswing upwardly from the pivotal point t on the arms t of the body as thebody swings downwardly, as will readily be understood on reference toFig. 1, where such tilted positions are illustrated in dotted lines. Thearms t of the scoop-body are provided with angular-shaped dogs M, pivoted thereto, against the inner arms, M", of which springs 22 bear toproject the arms M of said dogs forward to rest upon the top side of thescoop frame crossbar F, and through them the rear end of the body issupported; and a shaft, M, is hung above and parallel with saidcross-bar F in lugs 12 thereof,having dogs M extending downwardly andrearwardly to lie near or against the arms M of the dogs M on thescoop-arms, a coiled spring, a, by one end secured to said dog-shaft andby its other end to the crossbar, maintaining said dogs M. to a bearingby their ends upon the cross-bar; but by partially rotating said shaftthrough its handle-lever M in a manner to swing the rear ends of saiddogs outwardly and against the overlying and engaging ends of the dogs Mof the body, the rear end of said body is released from its engagementwith the cross-bar ofthe scoopt'rame and will, from the manner of itshanging and under its lead or its own weight, tip backwardly to dump.

N N represent shoes or runners upon the bottom of the scoop-bodyextending or incliir IIO esosw ing from their forward ends, a, which aresubstantlally flushvvith the under surface of the scoop-body downwardly,their rear ends be ing somewhat below said bottom. These shoes orrunners may be rigidly attached to the bottom, or adjust-ably attached,as shown, by securing their said forward ends, a, thereto, and formingtheir rear ends with an inward and returning bend, through a slot inwhich a headed pin, 20, screwing in and out of the bottom, projects, byits end or head maintaining the rear ends of the runners outwardly, asde sired.

In the operation of the wheeled scoop, with the scoopbody suspended inits uppermost position by the chains from the drums, held from unwindingby the pawls, as seen in Figs. 1 and 2, and it is desired to scrape andscoop dirt, &c., by pressing downwardly on the pawlarm at the pawls aremade to release the drum-ratchets, and said drums and their shafts arerotated under the unwinding of the chains supporting the scoop-frame,and from it the scoop-body, which descends to the ground, the incliningrunners forcing the forward end of the scoop downward to take to theground, too great a tip forward of the scoop being limited by the rearend of the body abutting against the crossbar F of the scoopframe; andwhen the tip of the scoop-body is adjusted by the runners for any depthof cut a pin should be passed through one of the holes 00 in thevertical guide-clasp bar F of the seoop-frame, through which thedraft-irons pass, above such draft-irons, in a manner to prevent theforward end of the scoop being forced too deep into the soil by thesuction caused by the resistance on the cutting edge,said cut ting-edgebeing below the line of draft. in other words, the lower the draft-ironsare confined by said pin the lower the line of draft is brought, and thelower the line of draft the less suction-power there is to draw thecutting-edge into the ground. Then as the carriage with the scoop movesforward the latter fills, and on throwing the lcvenarm L of disk L overto draw the connecting-rods inward, and through them the sleevesurrounding the yoke of the arm L away from its bearing upon theoverlying projection L of the cl utcheollar K, permitting saidsprocketed clutch, under the action of its spring, to be thrown intoengagement with the clutch K, which, causing the drum-shaft to rotate,winds up the chain and raises the scoop-body until such time as theclutches K are disengaged from the clutches K, which may be done at anytime during the raising of the scoop by throwing the lever L back intoits normal position shown, thus enabling it to be carried at any height,or when the scoopfralne rises to the height at which it is usual tocarry the same, by its projection E abutting against the incline L onarm L, the clutches K are then automatically thrown out of engagementwith the drunrshaft clutches and the winding discontinued. If desired,the inclined edge portion L of lever L may be adapted for bei ug adjustabl y seen red thereon, whereby an automatic throwing off of theparts described for securing the winding up of the chains may be securedwhen the scoopbody has reached any desired height.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1.
